Assuming the CD94 is the same, physically, as the CD94-II (which I think it is) then the the Marantz part number is 4822 410 25889.

I don't know if parts for a player this old are still available but if you wish to email me I will send you a scan of the page of ordering addresses from my CD94-II service manual. As I bought this about 15 years ago the list may be a little out of date so it may be as well to see if parts/service centres are given on the Marantz website.
